moved from the crank shaft extension in a simple and expeditious manner.

The nature and advantages of the inven tion will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in'the construction,combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a side elevation of the motor vehicle crank shaft extension,which forms a component part of my invention, the operating handle beingtherefore removed and an end cap being applied in its stead.

Figure 2 is a view similar to Figure 1, the said end cap being shown incross hand section.

F igure 3 is a view similar to Figures 1 and 2, but showing my removablecranking lever in position upon the end of said crank shaft extension.

Figure 1 is an end elevation of the" said cranking lever per se, and

Figure 5 is a perspective view of a collar member employed inconjunction with this invention.

Referring to the drawings in detail, my device constitutes the provisionof a shaft 5, having secured to the inner end thereof at 6 aconventional form of clutch" member 7. In the practical application ofmy device to Ford type of automobile, the usual crank shaft extension isremoved from its journal A after which my shaft 5 is positioned therein,in a manner more clearly shown in Figure 3.

After being positioned within the journal A, there is positioned uponthe shaft 5 a coll r 8, the same b g irc mf ntially grooved as at 9,formed at its front face with a pocket 10. Adjacent the outer end of thesaid shaft 5, there i positioned a cross pin 11, and encircling the saidshaft 5 between the cross pin 11, and the said collar 8 is a relativelystrong coil spring 12, the inner end thereof engaging within the saidpocket 10 of the collar for maintaining the same in face to face contactwith the adjacent face of the journal A as well as maintaining the saidclutch member 7 normally in face to face contact with the opposite endof said journal A.

The cranking lever designated 13 is a well known type, the upper endthereof being formed with a right angular extending head 14 within whichi a socket 15, the front end of the said head being slotted at 16 upondiametrically opposite sides thereof for the reception of the ends ofthe cross pin 11 of the shaft 5. e

In view of the above description, it will at once be apparent that theclutch member 7 upon the inner end of the shaft 5 is normally maintainedout of engagement with the co-operating clutch element upon the end ofthe motor crank shaft through the instrumentality of the coil spring 12Whenever it is necessary to crank the engine, the cranking lever may beexpeditiously placed upon the end of the shaft 5, this shaft engagingwithin the socket 15 of the head 14: at which time the shaft 5 may beslidinwardly of the journal A for consequently engaging the clutchelement 7 with the corresponding clutch element upon the end of themotor crank shaft, whereby through a turning movement of the crankinglever 13 the engine may be cranked. In Figures 1 and 2, I have shownacap 17 for the end of the shaft 5 when the cranking lever 13 is removedtherefrom. This cap consists of a relatively elongated and open endedcylinder formed at spaced points thereon with spring fingers 18, theends of which are curved inwardly of the said cap for forming heads 19which are adapted for engagement within the said circumferential groove9 of the collar 8.

In view of the above description, it is believed by me that theadvantages of a device of this character will be readily appreciated bythose skilled in the art, and although I have herein shown and describedthe preferred embodiment of my invention, it is nevertheless to beunderstood that minor changes may be made therein without departing fromthe spirit and scope of the in vention as claimed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

In combination with a shaft journaled in a bearing, a collar looselymounted upon. the shaft and hearing at one face against the shaftbearing, spring means confined at one end upon the shaft and bearing atits opposite end against the collar to hold the same in contact with thebearing shaft, said collar being provided with a circumferentiallylocated annular groove, a cap adapted to re ccive the end portion of theshaft and the said spring means, and adapted to snugly [it about theperiphery of the collar and bear at one end against the shaft bearing,and resilient arms out and formed up from the material of the cap anddisposed at spaced intervals around the cap, each of said arms having aninwardly disposed bend formed therein and in the vicinity of the freeend thereof'to provide heads which are friction- 25 ally received in thegroove of the collar.

In testimony whereof I afliX my signature.

MORRISE E. ROGERS.
